This Report of the Consultative Group of Experts to the subsidiary bodies contains three parts.

These elements are outlined as follows: national circumstances; national GHG inventories; vulnerability and adaptation assessment; research and systematic observation; GHG abatement analysis; education, training and public awareness; information and networking; and financial and technical support programmes. Part three of this report contains recommendations, based on the issues analysed in part two by the CGE relating to financial and technical support, improvement of the IPCC methodologies and other models, and improvement of the UNFCCC guidelines
